I use it as free phone s3x fodder. When they call me, I answer and pretend to be masturbating with heavy breathing and moans while answering their questions "yeessssss!", ask them to say things slower, and tell them to keep talking, etc., they usually hang up on me, but once I actually ended up whipping it out for real and was able to get off...
I have been getting a lot of calls from this number. It used to be one in the morning and one in the afternoon. But these last few days have been calling me at 6 pm and 8 pm. It is very annoying.
